I use a bogen/manfroto (OLD) for my 4x5s. No idea what the current incarnation is but it is sold as a rock. Not very light though. For the larger cameras I bought a cheap heavy chinese bogen copy because I needed one immediately and could not afford a name brand new. That sucker has held up through a LOT of abuse, including a drop off a cliff. I will replace it with a proper Manfrotto when I win the lottery this Wednesday.

I use a Manfrotto ball head on the little tripod and a pan tilt on the big one. Once again these are old and not sold under their old names any more.

I just counted up and both tripods and heads are over 15 years old.
